Chris, You will want to use protocol "C" which means that a write system call returns once it's completed on both systems. It ensures transactional atomicity. Also be absolutely sure you have same kernel and userlevel versions or you could seriously hose yourself when a failover happens.
Everything else takes a bit of time to figure out but it's not that hard.
